Problem with 3-way conferencing

manumehta · April 19, 2007, 11:01am

I am trying to achieve 3-way conferencing taking hint from wiki link http://www.voip-info.org/wiki/view/Asterisk+n-way+call+HOWTO

Here is the scenario:

user “ua1” calls user “ca1”
“ua1” then presses the feature code “*0” to redirect “ca1” to conference room 300
“ua1” then dials the user “33”
user “ua1” and “33” are connected
Now when “ua1” presses the feature code “**” to redirect user “33” to same conference room 300, there is error thrown on Asterisk console that “res_features.c:1415 ast_bridge_call: Bridge failed on channels SIP/ua1-ac750040 and AsyncGoto/Local/33@nway-conf-dest-7ecf,1”

Here is my dial plan:

[manu]
exten => ca1,1,Dial(SIP/ca1,wWtTkKrR)

[nway-conf]
exten => _.,1,Answer
exten => _.,n,Set(CONFNO=${EXTEN})
exten => _.,n,Set(MEETME_EXIT_CONTEXT=nway-conf-invite)
exten => _.,n,Set(DYNAMIC_FEATURES=)
exten => _.,n,MeetMe(${CONFNO},pdMX)
exten => _.,n,Hangup

[nway-conf-invite]
exten => 0,1,Read(DEST,dial,i)
exten => 0,n,Set(DYNAMIC_FEATURES=nway-conf-inv#nway-conf-noinv)
exten => 0,n,Dial(Local/${DEST}@nway-conf-dest,g)
exten => 0,n,Set(DYNAMIC_FEATURES=)
exten => 0,n,Goto(nway-conf,${CONFNO},1)
exten => i,1,Goto(nway-conf,${CONFNO},1)

[nway-conf-dest]
exten => _.,1,Dial(SIP/${EXTEN})

[macro-nway-conf-start]
exten => s,1,Set(CONFNO=300)
exten => s,n,ChannelRedirect(${BRIDGEPEER},nway-conf,${CONFNO},1)
exten => s,n,Read(DEST,dial,i)
exten => s,n,Set(DYNAMIC_FEATURES=nway-conf-inv#nway-conf-noinv)
exten => s,n,Dial(Local/${DEST}@nway-conf-dest,g)
exten => s,n,Set(DYNAMIC_FEATURES=)
exten => s,n,Goto(nway-conf,${CONFNO},1)

[macro-nway-conf-ok]
exten => s,1,ChannelRedirect(${BRIDGEPEER},nway-conf,${CONFNO},1)

The application map defined in features.conf is:
[applicationmap]
nway-conf-start => *0,self/caller,Macro,nway-conf-start
nway-conf-inv => **,self/caller,Macro,nway-conf-ok
nway-conf-noinv => *9,self/caller,Macro,nway-conf-notok

The output logs on Asterisk console:

Anyone??

Hi I know this is a very old post. But I’m trying to do this now and I was wondering if you figured it out?

Thanks!

Howdy,

Commenting on threads that have been silent for 11 years probably isn’t going to work-out very well.

Cheers

The 11 year old error looks like the result of using dialplan logic in a feature.
